What does it sound like to you?

Kelsey • I have been trying to conceive my second child for two years... I am so happy that it has finally happend!
So .... I got positive OPK on dec 10, dec 11, dec 12 and Dec 13. Alllll dark positives..
So for me I would count days past ovulation from the last day of positive OPK which would make me 19 DPO 
I took a pregnancy test on the 29th and it was negative but I have been moody, tierd my breasts have hurt for almost 2 weeks I got sick the other morning for no reason and things have been smelling kinda strong and irritating.. 
Also last week I had really heavy white creamy discharge.. It lasted for a few days then went to clear and light and now today I have creamy discharge again, not as heavy as last week but enough that in an hour I had more on my panties ... 
I have been pregnant before, and this is kind of how I remember the beginning being.. 
Could the test be wrong? 
Or do you think it's hormones?
